Different water treatment equipment is used for different sewage. Sewage treatment equipment is an industrial equipment that can effectively treat urban domestic sewage, industrial wastewater, etc., to prevent sewage and pollutants from directly flowing into the water. It is of great significance to improve the ecological environment, enhance the urban quality and promote economic development. Sewage treatment equipment is suitable for domestic sewage and similar sewage in residential areas, hospitals, sanatoriums, office buildings, shopping malls, hotels, restaurants, institutions, schools, troops, aquatic processing plants, livestock processing plants, dairy processing plants, etc. Similar industrial organic wastewater, such as organic wastewater treatment in textile, beer, papermaking, leather, food, chemical and other industries, mainly aims to treat domestic sewage and similar industrial organic wastewater to meet the reuse water quality requirements, so that the treated wastewater can be utilized as a resource. The existing sewage treatment method usually only sets a metal mesh in the sewage tank to block debris, and most of the filtering devices will cause sediment to block the filter after a certain period of use, thereby affecting the filtering effect. The filter device needs to be opened manually to clean the filter, which makes the entire use process complicated and the cleaning process is more cumbersome.

[0003] The Chinese utility model patent with application number: 202220935978.7 discloses a sewage purification device, including a sewage outlet box placed on the ground, a sediment filter screen is fixedly connected to one end of the sealing plate, a coagulant storage tank is fixedly provided at the upper end of the outer wall of the sewage box on the side opposite to the sealing plate, a pump integrated nozzle is installed at the upper end of the inner cavity of the sewage box, a feed pipe is fixedly connected between the pump integrated nozzle and the coagulant storage tank, and a pump plate is detachably connected to the bottom of the sewage outlet box. However, this type of sewage purification device filters sediment through a single-layer sediment filter screen structure, and the filtering effect is poor. After a certain period of use of the sediment filter screen, the sediment will clog the filter screen, thereby affecting the filtering effect. The filter device needs to be opened manually for cleaning. The separation process is relatively complicated and cumbersome, and the separation efficiency is low. Utility Model Content
